Renovation fraud is one of the most common and costly consumer scams in Canada. The Canadian Anti-Fraud Centre receives thousands of complaints annually from homeowners who paid deposits to contractors who vanished, received work far below what was promised, or were charged tens of thousands more than quoted. Recognizing the warning signs before you sign is how you protect your home — and your money.
| Step | Timeframe | Notes |
|---|---|---|
| Demands large upfront deposit (>20%) | Red flag #1 | Legitimate contractors have supplier credit. Large upfront deposits mean you lose leverage if work goes wrong. |
| Quote dramatically lower than competitors | Red flag #2 | If one quote is 40%+ lower, the contractor missed scope, is planning change orders, or won't complete the job properly. |
| No written contract offered | Red flag #3 | Legitimate contractors use written contracts. Working on a handshake protects the contractor, not you. |
| High-pressure 'sign today' tactics | Red flag #4 | 'This price is only good today' is a classic scam signal. Reputable contractors give you time to decide. |
| Can't provide proof of insurance | Red flag #5 | Demand a liability insurance certificate naming your property. Also verify WSIB/WorkSafeBC clearance. |
| No verifiable physical business address | Red flag #6 | A contractor with only a cell number and no verifiable address has nothing to lose if they do poor work. |
| Cash-only demands | Red flag #7 | Cash-only contractors often operate without legitimate business registration — and without accountability. |
Common across Canada, especially after storms: a truck appears offering to seal your driveway, fix your roof, or repair your foundation 'at a discount because they're working nearby.' These contractors almost universally do poor work with inferior materials and disappear when problems arise. Never hire any contractor who knocks on your door uninvited.
After major hail, wind, or flood events, predatory contractors appear in large numbers. Some pressure homeowners to sign 'assignment of insurance benefits' forms — which transfers your insurance claim to the contractor. This is legal in some provinces but significantly increases your risk. Always source contractors independently after storm damage.
In Ontario: verify electricians with the Electrical Safety Authority, plumbers with TSSA/Ontario College of Trades, home builders with HCRA. In BC: Consumer Protection BC for contractors, SkilledTradesBC for trades licences. All provinces: request a WSIB/WCB clearance certificate directly from the government website (not a screenshot) and an insurance certificate naming your property.
A contractor provides a very low initial quote to win the job, then presents 'unforeseen' additional costs once work is underway and you're committed. Protection: get detailed itemized quotes from three contractors, require signed change orders before any additional work begins, and never allow work to continue if cost overruns aren't approved in writing.
Licensing is province and trade-specific. Ontario: electricians via ESA (esasafe.com), plumbers via TSSA, home builders via HCRA (hcraontario.ca). BC: contractors via Consumer Protection BC (consumerprotectionbc.ca), trades via SkilledTradesBC. Alberta: check the Alberta Fair Trading Act and Skills Canada Alberta. Always verify licence numbers directly on the authority's website — not by asking the contractor.
Immediately: document everything (photos, all messages, the contract, payment records). File a police report — this is fraud. Report to your provincial consumer protection office (Consumer Protection Ontario, Consumer Protection BC, etc.). File with the Canadian Anti-Fraud Centre at antifraudcentre-centreantifraude.ca. If paid by credit card, initiate a chargeback. Pursue Small Claims Court (up to $35,000 in most provinces) if you can locate the contractor.
A legitimate renovation contractor requests 10–15% as an initial deposit, with additional payments tied to verified completion milestones. Never pay more than 25% before work begins. Final holdback (10–15%) should be retained until all deficiencies are addressed to your satisfaction. Any contractor demanding 50%+ upfront — regardless of their reason — is a significant warning sign.
HomeStars is one of Canada's largest contractor review platforms but reviews can be manipulated. Use it as one data point, not the only one. Cross-reference with Google Business reviews, the BBB, and personal referrals. The most reliable source remains referrals from people you know personally who've had similar work completed recently. Always independently verify credentials regardless of platform.
WSIB (Ontario) — and WorkSafeBC, WCB Alberta, CNESST Quebec, and equivalents in all provinces — provides coverage if a worker is injured on your property. If your contractor lacks coverage and a worker is hurt during your renovation, you can be held personally liable for medical costs and lost wages. Always request a clearance certificate directly from the provincial authority's website (wsib.ca, worksafebc.com, etc.) — never accept a printout or photo the contractor provides.
